Benefits of a Document Store and Triple Store Combined

Data Documents Triples

All the benefits of each, plus:

▪ Docs can contain triples, Triples can annotate docs, Graphs can contain docs

– Faster data integration using semantics as the glue

– Ideal model for reference data, metadata, provenance

– Ability to run really powerful queries

▪ Massive speed and scale

▪ Simplicity of a single unified platform

▪ Enterprise features (security, HA/DR, ACID transactions,…)

Single Learner ModelOmni-channel DIGITAL textbook experiences

Multi-Learner ModelOmni-channel adaptive learning experiences


Creating a Course: The ChallengeMeet MeredithMeredith is a Pearson Editor tasked with partnering with an established Author to develop a digital Psychology course designed to introduce students to psychology, promote critical thinking skills, and develop scientific writing skills.

She believes that the students targeted by this course will be most successful in meeting the course’s educational objectives if she adopts rich media and simulations.

She doesn’t know how to best reach into Pearson’s rich repository of proven instructional assets.

Problem Statement:How can Pearson help Meredith be successful in building a rich curriculum?

Solution:Multi-model approach that makes discovery of metadata enriched content possible through a simplified architecture.


Adaptive Learning: The ChallengeMeet AbigailAbigail is studying psychology and, while the early more theoretical chapters of her course were a breeze, the biological psychology chapters have been very challenging. As could be expected of a marathon runner - Abigail is determined to persist and succeed.

She has attempted the self-study quizzes and in each section has not succeeded. She doesn’t know what to do next to get past her hurdle.

Problem Statement:How can Pearson help Abigail to meet her learning objectives?

Solution:Adaptive / personalized learning
